Two Nvidia graphic cards
Hi, All

I've got 2 Nvidia cards. Now, I want both of them in the same computer. That seemed to be a little bit of trouble. I've been spending the last days googleing around the Net to find any How-tos, guides or a step-by-step tutorial, but nothing seems to help.

Does anyone have a clue?

I think that you may have to manually configure your xorg.conf file. You would need to setup the cards separately, using their PCI ID number. When you run this command, that number is at the beginning of the line.
Code:
lspci
So, my laptop has this:
Code:
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
I'm not sure which one to use, but I would have to include one of these in the section of xorg.conf that specified that card:

00:02.0
00:02.1

I don't have an example, but I have seen some distros include this info in the xorg.conf file. I hope this was of some help, and gives you a direction in which to procede in.

A little Googling found some help. Here's a little How-To, read the section titled "Configuring the graphic card"

Linux.com :: Editing basics for the xorg.conf file

And here is an example of the xorg.config section and how the entry might look:
Code:
Section "Device"
    Identifier  "ATI Radeon Xpress 200 Series"
    Driver      "fglrx"
    Option        "VideoOverlay" "on"
    Option        "OpenGLOverlay" "off"
    BusID       "PCI:1:5:0"
EndSection
Just make note of the BusID entry.

Hi there....

I've used lspci, and hardcoded/edited the xorg.conf file. Still nothing. I've however managed to switch back and fourth by changing the BusID and restarted X. But I am not able to have a picture on both screen at the same time.

Other suggestions?

You would need two separate Device entries, one for each card. I think that you would call them Device1 and Device2, but again not sure on this. Each Device would contain all of the info for the specific card.

Does the nvidia-settings application do some of this for you?

Aha!

When in doubt, RTFM! I should have done this first.

Here's the section of the nVidia README file concerning this.

Chapter 15. Configuring Multiple X Screens on One Card

As you can see, I was close, BUT WRONG.

Than U.

I've tried to give each card and monitor a seperate section, but ...

I'll try :
"Chapter*15.*Configuring Multiple X Screens on One Card"

and chang the BusID.

First, that was directed at myself, not you.

I edited the original post and added a link to it's meaning. It's a naughty word! LOL!
